Pro iDSD

Our Pro iDSD is for all music lovers, looking for their stairway to heaven.  It’s a DAC and so much more. It will take your music, movies and gaming to new heights.

A hi-res trinity

Our flagship Pro iDSD is for those who like music in all its flavours, especially high spec. It’s a standalone unit, a streamer and a DAC/amp

And with the option to listen in solid-state, tube or tube+, there’s something for everyone.

iFi audio Pro iDSD

DSD1024. Dizzy heights.

The Pro iDSD plays all high quality files from MP3 up to DSD.

It plays MQA and, for the first time, it brings Studio Grade DSD1024 to a wider audience – a rare feat. You are well and truly future-proofed.

All controlled from the palm of your hand via an app.

With added muscle

As with most iFi gear, we added filters to add flavour to your listening.

Check out the GTO filter. Just like the American muscle car, it adds weight and a new dimension to your driving…sorry, listening.

We’ve also given you Bit PerfectBit Perfect+Apodising, and Transient Aligned.

Curious mind? User Manual, page 16.

iFi audio Pro iDSD


Choose a wireless connection to stream your favourite tunes from Tidal, Spotify, Napster – the list is endless.

Take it up a notch by using a wired Ethernet connection to play from a router or NAS (Network Attached Storage).

Or relax with AirPlay to enjoy playback from your iPhone, iPad or Mac.

To USB or not to USB

Use USB Type A to connect a hard disk drive or a memory stick or Type Bto connect a laptop or server.

Or slot in a micro SDHC card with music files for instant playback.

Enjoy soulful tunes from your CD transport and enhance your gaming or movie experience as you connect via the coaxial/digital input.

Sound has never sounded so good.

Mood music

Finally, we’ve given you a choice of headphone sockets and outputs to cover all tastes. Big ones, little ones, balanced ones…

The Pro iDSD now currently comes in two ‘balanced’ versions – with 4.4mm or 2.5mm (discontinued) balanced headphone sockets. You choose which version you need.

So, whatever your mood, however you connect or listen, the Pro iDSD has an option for you.

The Pro iDSD has a 'quad 'stack' of Bit-Perfect DSD and DXD DACs by Burr-Brown. The 'interleaved' configuration means up to 8 pairs of differential signals can be used and mixed, equal to 4 pairs of signals per channel.

Full lowdown? User Manual, page 13.


The Pro iDSD employs the new XMOS XU216 X-Core 200 Series 16-Core processor. All-digital processing is Bit-Perfect unless particular digital filters are explicitly selected.

Explore the XMOS here.


Upsampling to DSD1024 has previously only been available to a select few. The Pro iDSD makes it available to a wider audience. The DSD1024 remastering is handled by the Crysopeia® FPGA and this is where we believe the FPGA excels.

Discover more on page 15 of the User Manual.


Listen to Master Quality Authenticated audio straight out of the box. Connect to Tidal Masters and check the option to stream MQA.

Our video tutorials on You Tube show you how.


Data is sent to the Memory Buffer from all inputs. Here it is de-jittered to eliminate any transmission of source jitter to the DAC output. The data from the Memory Buffer is further re-clocked by the low-jitter Global Master Timing® clock, which also drives the X-Core 200 and FPGA. 

With LINKPLAY™ WiFi/network playback, built-in Spotify and Tidal, and wide protocol support for 32-Bit/192kHz and DSD64, the Pro iDSD can be also used without a computer to stream audio directly.


Galvanic isolation is the ‘holy grail’ of computer audio.

All inputs are galvanically-isolated (including USB). The USB input section has its own separate power management system with multiple regulators and filtering operating from the galvanically-isolated voltage generated to power this section.


Unlike other amplifiers that have the same circuit and just switch in/out the tube section, the Pro iDSD is the very first of its kind to have two individual input circuits - one tube (General Electric 5670 tubes!) and one solid-state. This results in the 'best sonics of both worlds'.

Read more. Page 7.

We've given the Pro iDSD an extra Tube+ setting. This reduces overall loop-gain and negative feedback to the minimum and presents a different sonic perspective between the tube’s natural harmonics and transient performance.

Sound it out in the User Manual, page 7.


The amplifier audio circuit is fully discrete, fully-balanced with either tube or J-FET input switchable, bipolar second stage and MOSFET-buffered bipolar Class A Power stage.

The Pro iDSD is packed full of premium components - a Japan Alps rotary volume potentiometer, audio-grade ELNA Silmic capacitors and a bank of Elna Dynacaps ‘super capacitors’.

Discover how these benefit the Pro's unique design here.
